off grid power systems

You know that tumblr post that’s been going around about raising a kid with 5 of your friends?
Ok but think about this: a conglomerate of tiny houses, completely self-sustaining, somewhere in the city or accessible by public transportation
A baby
More than one goat (goats will cry if they’re alone)
Buns
Chickens hangin out
A large garden for growing our food
Plus rooftop gardens too
Hella solar powered
Off grid water systems
Everyone shares chores and food and everything else
Vermicomposting (Listen this shit is so cool)
Also hella hydroponics/aquaponics
I don’t know I think that not only is this a sustainable way to live but it would also reduce so many costs and how do I make this my future???
